Reservoir Working

North Third Reservoir (Stirlingshire) Maintenance & Interest of Safety Works

North Third Reservoir is an impounding reservoir on the Bannock Burn and although no longer used as a raw water supply source, maintenance work was required following an inspection by the Panel Engineer under the Reservoirs Act.

The main elements of work comprised:

  • Steelwork repairs & painting of the valve tower access
  • Structural repairs within the valve tower
  • Fabrication and installation of a new walkway through the valve tower culvert access
  • Renewal of the dam embankment drainage
  • Installation of new scour valve to improve reservoir control
  • Vegetation clearance and pitching repairs to both upstream and downstream wave wall faces and spillway channel
  • Dowelling and re-bedding of wave-wall coping stones

Special care had to be taken to ensure the working areas were kept safe and secure in this particularly scenic area which is popular with walkers and ramblers.

Undertaking the work during the winter required close monitoring of reservoir levels and scour operations to ensure safe access to the working areas.
